MedicaMetrix Signs Letter of Intent to Use Vytex® Natural Rubber Latex as Material of Choice in ProstaGlove™

ATLANTA, April 19, 2011 /PRNewswire/ -- Vystar® Corporation (OTCBB: VYST), the creator of Vytex® Natural Rubber Latex (NRL), a multi-patented, all-natural raw material that contains significantly reduced levels of the antigenic proteins found in natural rubber latex, announces that urological medical device manufacturer MedicaMetrix, Inc. has signed a Letter of Intent to use Vytex NRL as the material of choice in its ProstaGlove™, a diagnostic device currently in clinical trial development for the quantitative, physician office-based measurement of prostate cancer.

ProstaGlove, while still in development, is being designed to improve the diagnosis of prostate cancer by enabling the use of PSA density (PSAD) as a screen, in conjunction with PSA, to reduce unnecessary prostate biopsies with a proposed future net savings in prostate cancer diagnosis (after ProstaGlove sales), currently forecasted at more than $400 million in the US and $1 Billion globally.  ProstaGlove, when approved for use and sale, expects to enable the low-cost determination of prostate volume and PSAD, which could potentially eliminate hundreds of thousands of biopsies and could save hundreds of millions of dollars annually in the US in the cost of diagnosing prostate cancer.

Christopher G. LaFarge, Chief Executive Officer of MedicaMetrix, said, "MedicaMetrix has developed a system for the quantitative measurement of prostate volume that we believe will become the new 'gold standard' for prostate exams.  ProstaGlove will allow measurement of prostate volume and determination of PSAD to identify patients with elevated PSA appropriate for prostate biopsy. We believe that the physical characteristics of Vytex NRL, including its durability and tactile sensitivity, lend it the potential to be a superior choice of material for our products."

"The benefits of Vytex NRL are being recognized by professionals across a diverse base of industries," commented William R. Doyle, president and CEO of Vystar Corporation. "We look forward to enhancing our relationship with MedicaMetrix as they continue their quest to improve the standard of care for prostate cancer screening.  If MedicaMetrix is successful in making the ProstaGlove a 'gold standard,' our agreement has the potential to provide a significant market opportunity for Vytex NRL ."
